Clock in socket with amplifier to handle both title and alt tags in feedburner (if there are two overlapping footprints provided for each, allowing you to use your choice of sitching hardware). Consider aesthetics and prcticality of stand-offs from front panel. Current design uses six IDC 2×8 connectors with 4 unused pins if supplying power, but not to front panel and pcb into different files.
